s claims. (ci. 155-185) My invention aims to provide improvements in by a rivet or tack which, if desirable, may be cushion tufting structures and tufting devices formed as an integral part of the clip, as shown for the same. in Fig. 7, or may be a separate member, as shown In the drawing which illustrates preferred emin Figs. 3 through 6, inclusive. bodiments of my inventionz- The particular clip which I have found to work 5 Figure 1 is a vertical section through a portion very satisfactorily is formed from sheet metal of a seat cushion structure showing my improved and the fold-engagingportion is bent into a subtufting device; y f Y stantially U-shaped form having side portions II Fig. 2 is an enlarged section of the folded 'porand I2 (Figs. 3 and 5). The attaching member tion of the spring covering means, one of my irnfor the unit is in the form of a hollow tack sub- 10 proved tufting clips being shown in side elevastantially like that illustrated and described in tion; United States Letters Patent to Gustav John- Fig. 3 is a side elevation of a tufting clip before son No. 1,931,728. issued October 24, 1933, and attachment; has a base I3 and a sharp pointed hollow shank Fig. 4 is a plan view of the device shown in I4. The attaching tack has a pair of ears I5-I5 15 Fig- 3; cut from the base and wrapped about the side I2 Fig. 5 is a section taken on the line 5 5 of of the clip I0 in such a manner that' the sharp Fig. 4I pointed shank passes through an aperture I6 in Fig. 6 is a section taken on the line 6 6 of the side I2 and extends toward the other side II.

Fig- 3; 'I'he side II is also provided with an aperture I1 20 Fig. '7 is a side elevation of a tufting clip formed through which the shank Il of the tack may pass from a single piece of metal; and when the clip is attached to the seat upholstery. Fig. 8 is a section through one end of a clip To attach my improved tuftihg Clip, it is merely showing another arrangement of clip and tack. necessary to enter the fold 5 into the clip between Referring to my invention as illustrated by the the side II and the end of the tack I 4 and then 25 annexed drawing, Ihave shown, rather generally, squeeze the sides II and I2 toward each other a seat cushion structure which includes a spring thereby forcing the tack through the material unit including the usual coil springs I positioned of the fold 5 and through the aperture I1 in the between, and supported by, a frame 2 located side II of the clip I0. Thereafter the sharp underneath the coil springs, and another frame pointed end of the Shank i4 iS upset 0r riveted 30 2 on top of the springs and the structure also against the side Il to hold the clip securely in p0- including the upholstered covering supported by Sltion. aSshOWn in Fig. 2.

1. A seat cushion structure including a pair oi' spaced frame structures and spring means positioned between said frame structures, a padded cushion member on one of said frame structures, a covering for said member having a fold, a tufting device secured to said fold and being in the form of a U-shaped sheet metal clip having an attaching portion extending from one side thereof, said attaching portion being in the form of a sharp pointed tack extending through the fold at a point below the ends of said clip and through a hole in the other side and having its end portion upset and tie means connecting the clip to the lower of said frame structures to hold the fold under tension.

2. A tufting device of the class described formed from sheet metal and comprising a portion bent into substantially U shape, a tack having a base resting against one side of one of the sides of the U-shaped portion and having integral attaching portions engaged with the said side to secure the tack in position, and said tack having a hollow sharp pointed end extending from said base toward the other side.

3. A seat cushion structure including a pair of spaced frame structures and spring means positioned between said framestructures, a covering for said cushion having a downwardly extending fold, a U-shaped sheet metal tufting device having a leg extending upwardly at each side of said fold, said legs cooperating to grip the fold between them from the free ends of said legs to a point on each leg substantially below the free ends for the purpose of drawing opposite sides of said fold toward each other, a rigid attaching member extending from one leg of said tufting device at a point below the i'ree end thereof ,l through said fold and through the other leg to secure the device to the fold, said attaching member being completely concealed by the drawn-in sides of said fold and tie means connecting the tufting device to a spaced frame structure to hold the fold under tension.

4. A tufting device-of the class described comprising a member of substantially U-shaped cross-section having opposed sides connected by a loop at one end, said portion adapted to be bent only at said loop whereby said opposed sides may be moved toward one another, a rigid attaching member extending from one side of the U at a point spaced from the free end o1' that side toward the other side, and said other side having an aperture therethrough opposite the attaching member and spaced from the free end of said other side at a distance equal to that between the attaching member and the free end of said rst side, said aperture adapted to receive said attaching member when the device is attached to a cushion structure. A

5. A tufting device of the class described comprising a member of substantially U-shaped cross-section having opposed sides connected by a loop at one end, said portion adapted to be bent only at said loop whereby said opposed sides may be moved toward one another, a rivet extending from one side of the U at a point spaced from the free end of that side toward the other side, and said other side having an aperture therethrough spaced from the free end of said other side at a distance equal to that between the attaching member and the free end of said rst side. said rivet adapted to pass through said aperture and have its end portion upset when the device is attached to a cushion structure.

6. In a cushion construction, spaced frame structures, spring means positioned between said frame structures, a padded cushion member on the outside of one of said frame structures, said cushion member having a covering having a fold extending downwardly, a plurality of individual tufting devices secured to the fold of the covering and having spaced means bearing against opposed sides of said fold, means connecting said spaced bearing means, each of said tufting devices being completely concealed by the covering, and tie means connecting the tufting devices to the other frame structure to hold the fold under tension.
